Description

Technical Field

[0001] The utility model belongs to the technical field of plastic pelletizing, and in particular relates to a modified plastic pelletizing device. Background Art

[0002] Modified plastics refer to plastic products that are modified on the basis of general plastics and engineering plastics through filling, blending, reinforcement and other methods to improve the flame retardancy, strength, impact resistance, toughness and other properties. When they need to be processed, modified plastic pelletizing equipment is needed to pelletize them, so as to facilitate subsequent processing.

[0003] In actual use, the existing modified plastic pelletizing device will produce debris and powder when pelletizing the modified plastic due to the cutting of the blade. These debris will be mixed with the cut plastic particles and collected in a designated location, and personnel are required to perform secondary screening, which makes the process of the finished product complicated and inconvenient to use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a modified plastic pelletizing device, which has the function of screening and can screen out debris and powder.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modified plastic pelletizing device, comprising a base plate, two support plates are fixedly connected to the top of the base plate, a cutting box is fixedly connected between the two support plates, two correspondingly distributed transmission wheels are arranged on the outside of the cutting box, a transmission belt is transmission-connected between the two transmission wheels, a connecting rod is fixedly connected to the outside of the cutting box, a first motor is fixedly connected to the end of the connecting rod away from the cutting box, an output end of the first motor is fixedly connected to one of the transmission wheels, two correspondingly distributed rotating drums are rotatably connected inside the cutting box, a plurality of correspondingly distributed cutting knives are fixedly connected to the outsides of the two rotating drums, the two rotating drums are respectively fixedly connected to the corresponding transmission wheels, an adjustment mechanism is arranged on the top of the cutting box, and a rolling mechanism is arranged on the top of the base plate.

[0006] Preferably, the rolling mechanism includes a fixed block, which is fixedly connected to the top of the base plate, a second motor is fixedly connected to the inside of the fixed block, a gear is fixedly connected to the output end of the second motor, a support block is fixedly connected to the top of the base plate, a roller is rotatably connected to the top of the support block, a gear ring is fixedly connected to the outside of the roller, and the gear ring is meshed with the gear.

[0007] Preferably, a plurality of correspondingly distributed screening holes are provided on the outside of the drum, a rotating cover is rotatably connected to the outside of the drum, and a blanking plate is provided between the rotating cover and the cutting box.

[0008] Preferably, the adjustment mechanism comprises a turntable, which is rotatably connected to the top of the cutting box. A limiting groove is provided on the outside of the cutting box, and a bidirectional screw rod is rotatably connected inside the limiting groove.

[0009] Preferably, the external threaded connection of the bidirectional screw rod is connected to two correspondingly distributed adjustment plates, and the interiors of the two adjustment plates are both rotatably connected to a rotating column.

[0010] Preferably, two ends of the blanking plate are respectively connected to the rotating cover and the cutting box, and the roller is arranged at an angle.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When it is necessary to screen the plastic particles, first start the second motor, and drive the gear to rotate through the output end of the second motor. Because the gear and the gear ring are meshed, and the gear ring and the roller are fixedly connected, the gear will drive the roller to be subjected to force when it rotates. Because the rotating cover and the roller are rotationally connected, the roller also rotates when the gear rotates. When the modified plastic is pelletized, the cut plastic particles are brought into the cutting box by the force of the cutter, and then fall into the unloading plate through the cutting box. Then the plastic particles pass through the unloading plate into the inside of the roller, and the rotation of the roller drives the plastic particles to roll. At this time, the debris and powder generated when the plastic particles are cut will be discharged through the screening holes to achieve the screening effect. Through the above mechanism, the modified plastic cut into particles can be screened, so that the debris and powder generated during cutting can be screened out to avoid the debris from mixing with the cut plastic particles and collecting them at the designated location, thereby avoiding the secondary screening work of subsequent personnel and reducing subsequent processing procedures.

[0013] 2. When the modified plastic is being cut, first put the modified plastic between the two rotating columns, then rotate the turntable, and the rotation of the turntable drives the bidirectional screw to rotate. Because the two adjustment plates and the bidirectional screw are threadedly connected, and because of the limit groove, when the bidirectional screw rotates, the two adjustment plates are close to each other, and at the same time drive the rotating columns close to each other, so as to clamp the modified plastic. At the same time, the adjustment plate and the rotating column are rotationally connected, so it does not affect the modified plastic to approach the cutter. Through the above mechanism, the operator can make it more stable when cutting the modified plastic, and the cutter can make the blade smoother when cutting the modified plastic.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] See also Figure 1-4 The utility model provides a technical solution: a modified plastic pelletizing device, comprising a bottom plate 1, two supporting plates 4 are fixedly connected to the top of the bottom plate 1, a cutting box 5 is fixedly connected between the two supporting plates 4, two correspondingly distributed transmission wheels 8 are arranged outside the cutting box 5, a transmission belt 9 is transmission-connected between the two transmission wheels 8, a connecting rod 6 is fixedly connected to the outside of the cutting box 5, a first motor 7 is fixedly connected to the end of the connecting rod 6 away from the cutting box 5, an output end of the first motor 7 is fixedly connected to one of the transmission wheels 8, two correspondingly distributed rotating drums 10 are rotatably connected inside the cutting box 5, a plurality of correspondingly distributed cutting knives 11 are fixedly connected to the outsides of the two rotating drums 10, the two rotating drums 10 are respectively fixedly connected to the corresponding transmission wheels 8, an adjusting mechanism 3 is arranged on the top of the cutting box 5, and a rolling mechanism 2 is arranged on the top of the bottom plate 1.

[0022] In this embodiment, when the modified plastic is pelletized, the first motor 7 is first started, and the output end of the first motor 7 is rotated to drive one of the transmission wheels 8 to rotate, and the transmission belt 9 is used to drive the other transmission wheel 8 to rotate. Because the transmission wheel 8 and the rotating drum 10 are fixedly connected, when the transmission wheel 8 rotates, it drives the rotating drum 10 to rotate, and the cutter 11 also rotates accordingly, thereby cutting the modified plastic into particles. The modified plastic cut into particles can be screened by the rolling mechanism 2, so that the debris and powder generated during the cutting are screened out to prevent the debris from mixing with the cut plastic particles and collecting them to the designated location, thereby avoiding the secondary screening work of subsequent personnel and reducing the subsequent processing steps. The adjustment mechanism 3 can make the operator more stable when cutting the modified plastic, and the cutting edge of the cutter 11 is smoother when cutting the modified plastic.

[0023] Embodiment 2:

[0024] See also Figure 1-3 On the basis of the first embodiment, the utility model provides a technical solution: the rolling mechanism 2 includes a fixed block 201, the fixed block 201 is fixedly connected to the top of the bottom plate 1, the fixed block 201 is fixedly connected to the second motor 202, the output end of the second motor 202 is fixedly connected to the gear 204, the top of the bottom plate 1 is fixedly connected to the support block 203, the top of the support block 203 is rotatably connected to the roller 207, the outside of the roller 207 is fixedly connected to the gear ring 208, the gear ring 208 is meshed with the gear 204, a plurality of correspondingly distributed screening holes 209 are provided on the outside of the roller 207, the outside of the roller 207 is rotatably connected to the rotating cover 205, a blanking plate 206 is arranged between the rotating cover 205 and the cutting box 5, the two ends of the blanking plate 206 are respectively connected to the rotating cover 205 and the cutting box, and the roller 207 is arranged at an angle.

[0025] In this embodiment, when it is necessary to screen the plastic particles, the second motor 202 is first started, and the output end of the second motor 202 drives the gear 204 to rotate. Since the gear 204 is meshed with the gear ring 208, and the gear ring 208 is fixedly connected to the roller 207, the gear 204 will drive the roller 207 to be subjected to force when it rotates. Since the rotating cover 205 is rotatably connected to the roller 207, the roller 207 also rotates when the gear 204 rotates. When the modified plastic is pelletized, the cut plastic particles are brought into the cutting box 5 by the force of the cutter 11, and then the cut plastic particles are removed by the cutting box 5. The plastic particles pass through the cutting box 5 and fall into the blanking plate 206. Then, the plastic particles pass through the blanking plate 206 and enter the interior of the drum 207. The rotation of the drum 207 drives the plastic particles to roll. At this time, the debris and powder generated when the plastic particles are cut will be discharged through the screening holes 209 to achieve the screening effect. Through the above mechanism, the modified plastic cut into particles can be screened, so as to screen out the debris and powder generated during cutting, and avoid the debris from mixing with the cut plastic particles and collecting them to the designated location, thereby avoiding the secondary screening work of subsequent personnel and reducing the subsequent processing steps.

[0026] Embodiment three:

[0027] See also Figure 1-4 On the basis of the first and second embodiments, the utility model provides a technical solution: the adjustment mechanism 3 includes a turntable 301, the turntable 301 is rotatably connected to the top of the cutting box 5, a limiting groove 302 is provided on the outside of the cutting box 5, a bidirectional screw rod 303 is rotatably connected inside the limiting groove 302, and the external thread of the bidirectional screw rod 303 is connected to two correspondingly distributed adjustment plates 304, and the insides of the two adjustment plates 304 are both rotatably connected to a rotating column 305.

[0028] In this embodiment, when the modified plastic is being cut, the modified plastic is first placed between the two rotating columns 305, and then the turntable 301 is rotated. The rotation of the turntable 301 drives the bidirectional screw rod 303 to rotate. Because the two adjustment plates 304 and the bidirectional screw rod 303 are threadedly connected, and because of the limitation of the limiting groove 302, when the bidirectional screw rod 303 is rotating, the two adjustment plates 304 are close to each other, and at the same time, the rotating column 305 is driven close to each other, thereby clamping the modified plastic. At the same time, the adjustment plates 304 and the rotating column 305 are rotationally connected, so it does not affect the modified plastic from approaching the cutter 11. Through the above mechanism, the operator can make it more stable when cutting the modified plastic, and the cutter 11 can make the blade smoother when cutting the modified plastic.

[0029] The working principle and use process of the utility model are as follows: when it is necessary to screen the plastic particles, first start the second motor 202, and drive the gear 204 to rotate through the output end of the second motor 202. Because the gear 204 is meshed with the gear ring 208, and the gear ring 208 is fixedly connected to the roller 207, the gear 204 will drive the roller 207 to be subjected to force when it rotates. Because the rotating cover 205 is rotationally connected to the roller 207, the roller 207 also rotates when the gear 204 rotates. When the modified plastic is pelletized, the cut plastic particles are brought into the interior of the cutting box 5 by the force of the cutter 11, and then fall into the blanking plate 206 through the cutting box 5. Then the plastic particles pass through the blanking plate 206 and enter the interior of the roller 207. The rotation of the roller 207 drives the plastic particles to roll. At this time, the debris and powder generated when the plastic particles are cut will be discharged through the screening holes 209, thereby achieving the screening effect.

[0030] When the modified plastic is being cut, the modified plastic is first placed between the two rotating columns 305, and then the turntable 301 is rotated. The rotation of the turntable 301 drives the bidirectional screw rod 303 to rotate. Because the two adjustment plates 304 and the bidirectional screw rod 303 are threadedly connected, and because of the limitation of the limiting groove 302, when the bidirectional screw rod 303 is rotating, the two adjustment plates 304 are close to each other, and at the same time, the rotating column 305 is driven close to each other, so that the modified plastic is clamped. At the same time, the adjustment plates 304 and the rotating column 305 are rotationally connected, so it does not affect the modified plastic from approaching the cutter 11. Through the above mechanism, the operator can make it more stable when cutting the modified plastic, and the cutter 11 can make the blade smoother when cutting the modified plastic.
